New Carb Intake Cant get engine to start now please help

I have a chevy 350. I just replaced the QJet carb with a brand new Edelbrock Performer 1406 and a Performer intake. New cap rotor plugs wires. New fuel pump, clear fuel filter.
Put it all back together and I am now trying to start it up and it wont start.
I have fuel, can see it in the filter as well as in the carb.
I have spark. I hooked up a spark tester to the number 1 cylinder plug wire and grounded it and it sparks perfect.
I thought maybe I was 180 out so I poped the cap off did a 180 same thing. Nothing. I put it back where I had it the first time.
I even double checked to make sure I had the firing order right, twice. All wires hooked up in the correct order.
I marked the distributor housing to the hold down so I know its right where it was when I took it out. I even tried advancing and retarding as we cranked it over nothing. Just a pop out of the carb when I went to far.

It just wont start.
Any suggestions???? Im lost. Really no idea what to try next.
I really needed to have it running by tomorrow after noon.
Please help.
Thanks in advance for any suggestions.
